un;smme nnmon:

Y '0 all 10 wm 2'25 mag conce7m Be it.known that I, Roninfn a citizen oftheUriited States, .resxdingat Chicago, in the county of (look State oi liinois, have invented neW andj usefnl improvementg in Ti&Spacing Devises, ,ofwhich the following is a full, cl&lcon; cise, and exact description, refeirenee being lied to the nccoinpanying di*awing, formiigg, a part of this speifiatiod liy invention relates to i npto en ents,in tie-spacing;devioes. V

One: objeot of the inventionis toprovidea devise whioh maybe n5ed .eithen io1: spaCing the tics on a bridge or for distflbutingthe thri st of an anti-creepenovel: flWobr. inore tics. g

inother object is to, provide a tie sPaoer" which may be readily appliedorjrenawed,

: without necessitating lifting the rail fizom the tie 01: otherwise distnrbing the tr.iok;

Further objects. will be apparent fio 1ntbefollowihg description.

In the aociompanying drmvings, I: have illnstrated a tie spacer Which embodies,my invention. Ido not desire to liinit myself, howex*er, to tlie strnctnralform disclosed:as varions modifications may be made therein.

Figure 1 is a top plan x 'ieW of a portion of a railway track on a bridge, Eig .2isa side elevation thereof. Fig, is a perspective xieW on an enlargedsoale ofthe tie spacer. 4 is a b'ttom VieW thereof. Fig. is a top plan view of.a short length of railway track showing the tie spacer;

used in combination with an anti-creeper.

The portion of the bridge fioor shown in Figs. 1 and 2 comprises the usual cross-ties 1 snpported on stringers 2 and having guard rails 3 arranged at the onter ends thereof. Rails are supported on the cross-ties in the usual manner. In order to maintain the crossties in proper sp1ced relation, I provide tie spacing devices 5 arranged at both ends of the ties and preferably between the rail and the guard rail. The tie spacers are thus independent of and do not interfere with the use of the ordinary (fie-plates 6, where the latter are desirable. The tiespacer in the iorm illustrated, is a casting oif malleable iron, cast iron or other snitable material, and is provided with a pair of downwardly extending flanges 7 near the opposite ends thereof. Said fianges are quite deep as compared to the width of the speqifiaa.tion of Lettens;Pafaent.,

alijg c1uite, regnlar,, however, being sawed to;a un ifym cross.,section and acc0rdingly Wli16 used with snob t1 es, the vert cal depth need not necessarily be as great as undr,

other conditions; of use, since the maximum vertical bearing surface proyidd b'y: said fianges,' 1s maniable, The sznd fianges are reifirCedby compression member 8, in: teg1gal therewith and preirably centraliy l0 catd, therebyadapting the tie-spaoen t0 transmit: an enormous thrust from one tie. to the 0ther. In order to avoid' an excesSively heavy casting, thecompression member is equivalent. means. Said tie-spacers need not ne essariiy be. ai*ranged outside. of the rails.

By us1ng tietpacerssnch as described' here1n, dappmg of the 'gi iaidrails, that is,,

notchingthem out, on the nnder side, may be d1spensed with, thenotched ont portions ,of the guard rail fit ofi er the ties thereby maintaining the latter in properspaced relation, The elimii1ation of the. dapping opeiyation.

results in increased econoiny, not only in the time and labor saved, but because of the facttbat a guard rail of smalier cross section may be nsed. In fact, by using steel rails as gnard rails, and locating the latter betWeen the regular rails, the wooden guard rails may be dispensed with entirety, although the fact that their use has become customary, may make it advisable to retain them for the sake of appearance. On 0rdinary railway tracks, tlie rail joints are prevented frcm advancing or creeping over the ties by the spikes which pass througli notches in the splice bars. In tracks, as eustomarily laid on bridges, the rail joints are not thus secured to the ties as creeping of the rails wonld resnlt in bunching up the ties unless clapping is made use of. By using my improved tie-spacer, however, the rail joints on bridges may be secured to the ties in the same wav that they are secured in ordinary ballasted track. This is due to the fact that all of the ties being rigidly road bed.

spaced H and interconnected, the creeping thrust may be distributed throughout all of said ties.

A further important shown in Fig; 5. The rail 11' is supported on crossties 12 which latter may be more or less irregular in cross section, or at least devoid cf square corners. :Tl1e anti creeper 18 is appliedto the rai] base adjacent to one of the 'ties in the customary manner. The anticreeper shown is intended to be tyPical of any standard anti-creeper. The tie spacers are applied to the ties' preferably outside of the rails, although not necessarily s0, one or tWo tiespacers being ordinrrily suflicient The anticreeper transmits the creeping thrust to the tie which it. engages, said tie transmitting a part of said thrust to the adjacent tie or tics so that the thrust is resisted by more than 011e tie. E ven if the ties are somewhat irregular,the depending flange 7 is sufiiciently deepto engage soma part of the Vertical face thereofto insure a firm seat. V

By usingany improved tiespacer in conjui1ction with an anticreeper, the number of anti-creepers employed may be much reduced. thereby efizeting a substantial economy, as the cost of the tie-spaers is much 7 less than the cost of the anti-oreepers.

A further advantage of my device is that by its use, it ispossible to keepthe tics substa11tially in their original position on the dation, The tendency of an anti-creeper, of

Gopieshf this patent may be obtained for use for the device is in con]nnct1on Wlth an ant1creeper, as

Since the ballast is worked uncourse, is to move the tie sidewise through the ballast. By using sufficient tiespacers, however, thistendency -is efiectually resisted and the initial firm foundation is made to serve its purpose indefinitely.

Of course, I do not desire to limit myself to a tie-spacer of cast 1netal as distinguished from one rolled or otherwise forrned, particularly as the devicemay be made in forms somewhat different from that illustrated, and hence adapted to a rolling operation. I desire, thetefore, to cover whatever suitable equivalent modifications may be devised Which fall Within the spirit of the invention.

Having thus described my invention, what I daim as new and desire to secure by Letters Patent of theUnited' States is:

V 1. A tie spacing device comprising a compression member in the form of a vertical Web having lateral bearing faces at opposite ends thereof adapted to be received between the sides of adjacent ties and having a rein forcing flange arranged longitudinztlly thereoi, said flange projecting beyond the web at opposite ends to provide supporting members arranged to rest on the tops of said ties out of contact With the rail.

In a railway track construction, the combination With a rail and a plurality of supp orting cross-tires therf0r, of compression members c01mprising vertical webs arranged in alinement' at one side of but parallel to the rail, and means' resting on the tops of said ties and integral with said webs for supporting them.
